8 | If you are ready to start working on any of these TODO items, we |
9 | appreciate your help; please write to emacs-devel@gnu.org so we can be | |
10 | aware that the problem is being addressed, and talk with you how to do | |
7bea57c9 | 11 | it best. Since Emacs is an FSF-copyrighted package, please be |
2255d5b4 RS |
12 | prepared to sign legal papers to transfer the copyright on your work |
13 | to the FSF. | |
14 | ||
ba1c68de | 15 | * Small but important fixes needed in existing features: |
a9c1a157 | 16 | |
81f2b1ae CY |
17 | ** Fix compilation when Xaw3d libraries are present but libxaw is not. |
18 | In new X11 versions, xaw3dg-dev does not depend on libxaw-dev, so the | |
19 | latter need not be installed. As a result, all the source files that | |
20 | look for include files in X11/Xaw should look in X11/Xaw3d if we are | |
21 | using Xaw3d. | |
22 | ||
0989e765 SM |
23 | ** Compute the list of active keymaps *after* reading the first event. |
24 | ||
444ad0f5 KS |
25 | ** Avoid using "iff" in doc strings. |
26 | ||
988ff018 KS |
27 | ** mouse-autoselect-window should wait to select the window until |
28 | the mouse is put to rest or after a delay or both, so that moving over | |
29 | a window doesn't select it. | |
30 | ||
55815819 RS |
31 | ** In C-x d, the default if you type RET should be the directory name, |
32 | but if you type M-n you should get the visited file name of the | |
33 | current buffer. | |
34 | ||
28cb9364 | 35 | ** describe-face should show an example of text in the face. |
8a8a1cbb | 36 | |
046ece71 KS |
37 | ** Distribute a bar cursor of width > 1 evenly between the two glyphs |
38 | on each side of the bar (what to do at the edges?). | |
39 | ||
e008f665 DN |
40 | ** Make vc-checkin avoid reverting the buffer if has not changed after |
41 | the checkin. Comparing (md5 BUFFER) to (md5 FILE) should be enough. | |
42 | ||
d322eb9b RS |
43 | ** buffer-offer-save should be a permanent local. |
44 | ||
125fbe81 RS |
45 | ** revert-buffer should eliminate overlays and the mark. |
46 | ||
f98abf6d RS |
47 | ** erase-buffer should perhaps disregard read-only properties of text. |
48 | ||
30c56b97 LT |
49 | ** Make occur correctly handle matches that span more than one line, |
50 | as well as overlapping matches. | |
51 | ||
d3a403e5 | 52 | ** Fix the kill/yank treatment of invisible text. At the moment, |
b9e6b498 | 53 | invisible text is placed in the kill-ring, so that the contents of |
2345130a SM |
54 | the ring may not correspond to the text as displayed to the user. |
55 | It ought to be possible to omit text which is invisible (due to a | |
b9e6b498 GM |
56 | text-property, overlay, or selective display) from the kill-ring. |
57 | ||
6f771c32 RS |
58 | ** Change the way define-minor-mode handles autoloading. |
59 | It should not generate :require. Or :require in defcustom | |
60 | should not be recorded in the user's custom-set-variables call. | |
61 | ||
af09dd78 RS |
62 | ** Feature to change cursor shape when Emacs is idle (for more than |
63 | a specified time). | |
64 | ||
4e07258f RS |
65 | ** The buttons at the top of a custom buffer should not omit |
66 | variables whose values are currently hidden. | |
67 | ||
ec0cf966 RS |
68 | ** Clean up the variables in browse-url. Perhaps use a shell command string to |
69 | specify the browser instead of the mushrooming set of functions. | |
70 | See also ESR's proposal for a BROWSER environment variable | |
71 | <URL:http://www.catb.org/~esr/BROWSER/browse-url.patch>. | |
72 | ||
528b6abc RS |
73 | ** Enhance scroll-bar to handle tall line (similar to line-move). |
74 | ||
75 | ** Make occur handle multi-line matches cleanly with context. | |
76 | ||
f98abf6d RS |
77 | ** In Custom buffers, put the option that turns a mode on or off first, |
78 | using a heuristic of some kind? | |
79 | ||
80 | ** Define recompute-arg and recompute-arg-if for fix_command to use. | |
81 | See rms message of 11 Dec 05. | |
82 | ||
7c14546c JD |
83 | ** Height returned by frame-parameter ... and height given to |
84 | make-frame does not mean the same thing. The former includes menu and | |
85 | tool bar lines, the latter don't. frame-parameter should return height | |
86 | without menu and tool bar lines. | |
87 | ||
f98abf6d RS |
88 | ** In Emacs Info, examples of using Customize should be clickable |
89 | and they should create Custom buffers. | |
90 | ||
321e4870 RS |
91 | ** The toolbar should show keyboard equivalents in its tooltips. |
92 | ||
74561a26 RS |
93 | ** Add function to redraw the tool bar. |
94 | ||
a9b6d67e RS |
95 | ** M-! M-n should fetch the buffer-file-name as the default. |
96 | ||
5a893bff RS |
97 | ** Redesign the load-history data structure so it can cope better |
98 | with evaluating definitions of the same function from different files, | |
99 | recording which file the latest definition came from. | |
046ece71 | 100 | |
4b4d11cc RS |
101 | ** make back_comment use syntax-ppss or equivalent. |
102 | ||
211fb124 | 103 | ** Improve configure's treatment of NON_GNU_CPP on Solaris. |
67ccd6cb GM |
104 | (patch available for after Emacs 22) |
105 | ||
106 | ** Consider improving src/sysdep.c's search for a fqdn. | |
107 | http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00782.html | |
108 | ||
109 | ** Find a proper fix for rcirc multiline nick adding. | |
110 | http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00684.html | |
211fb124 | 111 | |
ba1c68de | 112 | * Important features: |
a9c1a157 | 113 | |
ba1c68de | 114 | ** Provide user-friendly ways to list all available font families, |
321e4870 RS |
115 | list fonts, display a font as a sample, etc. [fx is looking at |
116 | multilingual font selection for the Unicode branch of Emacs.] | |
5e101746 | 117 | |
3aa7c28e RS |
118 | ** Provide a convenient way to select a color with the mouse. |
119 | ||
09d04fb3 RS |
120 | ** Rewrite the face code to be simpler, clearer and faster. |
121 | ||
ba1c68de | 122 | ** Program Enriched mode to read and save in RTF. [Is there actually a |
c51b37fd | 123 | decent single definition of RTF? Maybe see info at |
1b2105d9 EZ |
124 | http://latex2rtf.sourceforge.net/.] This task seems to be addressed |
125 | by http://savannah.nongnu.org/projects/emacs-rtf/, which is still in | |
126 | very early stages. | |
6165b6e3 | 127 | |
ba1c68de | 128 | ** Implement something better than the current Refill mode. This |
a9c1a157 RS |
129 | probably needs some primitive support. |
130 | ||
ba6be78d | 131 | ** Add a command to make a "Local Variables" section in the current buffer |
07ff1e4b RS |
132 | and/or add a variable to the list. |
133 | ||
ba1c68de | 134 | ** Implement primitive and higher-level functions to allow filling |
a9c1a157 RS |
135 | properly with variable-pitch faces. |
136 | ||
ba1c68de | 137 | ** Implement a smoother vertical scroll facility, one that allows |
d3a403e5 SM |
138 | C-v to scroll through a tall image. The primitive operations |
139 | posn-at-point and posn-at-x-y should now make it doable in elisp. | |
a9c1a157 | 140 | |
6ca1c497 RS |
141 | ** Implement intelligent search/replace, going beyond query-replace |
142 | (see http://graphics.csail.mit.edu/~rcm/chi04.pdf). | |
143 | ||
ba1c68de SM |
144 | ** Implement other text formatting properties. |
145 | *** Footnotes that can appear either in place or at the end of the page. | |
146 | *** text property that says "don't break line in middle of this". | |
6165b6e3 EZ |
147 | Don't break the line between two characters that have the |
148 | same value of this property. | |
ba1c68de | 149 | *** Discretionary hyphens that are not visible when they are at end of line. |
6165b6e3 | 150 | |
ec0cf966 RS |
151 | ** Internationalize Emacs's messages. |
152 | ||
4a7499a9 RS |
153 | ** Set up a facility to save backtraces when errors happen during |
154 | specified filters, specified timers, and specified hooks. | |
155 | ||
49322539 RS |
156 | ** Install mmc@maruska.dyndns.org's no-flicker change. |
157 | ||
07ff1e4b RS |
158 | ** Add a "current vertical pixel level" value that goes with point, |
159 | so that motion commands can also move through tall images. | |
160 | This value would be to point as window-vscroll is to window-start. | |
161 | ||
ec0cf966 RS |
162 | ** Address internationalization of symbols names essentially |
163 | as documentation, e.g. in command names and Custom. | |
a9c1a157 | 164 | |
ba1c68de | 165 | ** Make the Lucid menu widget display multilingual text. [This |
bf6394a6 DL |
166 | probably needs to be done from actual Emacs buffers, either directly |
167 | in the menu or by rendering in an unmapped window and copying the | |
f677a3a3 SM |
168 | pixels. The current code assumes a specific locale; that isn't good |
169 | enough even if X can render the arbitrary text] [The gtk | |
7bea57c9 DL |
170 | port now displays multilingual text in menus, but only insofar as |
171 | Emacs can encode it as utf-8 and gtk can display the result.] | |
f677a3a3 SM |
172 | Maybe making Lucid menus work like Gtk's (i.e. just force utf-8) is good |
173 | enough now that Emacs can encode most chars into utf-8. | |
a9c1a157 | 174 | |
ba1c68de | 175 | ** Remove the limitation that window and frame widths and heights can |
a9c1a157 RS |
176 | be only full columns/lines. |
177 | ||
ba1c68de SM |
178 | * Other features we would like: |
179 | ||
a37288ad SM |
180 | ** Remove the default toggling behavior of minor modes when called from elisp |
181 | rather than interactively. This a trivial one-liner in easy-mode.el. | |
a53e64cc SM |
182 | ** Create a category of errors called `user-error' for errors which are |
183 | typically due to pilot errors and should thus be in debug-ignored-errors. | |
184 | ||
39eadb4a RS |
185 | ** Give Tar mode all the features of Archive mode. |
186 | ||
9b8453da RS |
187 | ** Create a category of errors called `process-error' |
188 | for some or all errors associated with using subprocesses. | |
189 | ||
51f74c37 RS |
190 | ** Maybe reinterpret `parse-error' as a category of errors |
191 | and put some other errors under it. | |
192 | ||
1a500a73 | 193 | ** A function to tell you the argument pattern of functions. |
1b2105d9 | 194 | See `function-arity' in http://www.loveshack.ukfsn.org/emacs/fx-misc.el. |
1a500a73 RS |
195 | |
196 | ** Make byte-compile warn when a doc string is too wide. | |
197 | ||
9f4ba075 CY |
198 | ** Make byte-optimization warnings issue accurate line numbers. |
199 | ||
f95a20e7 RS |
200 | ** A function to check for customizable options that have been |
201 | set but not saved, and ask the user whether to save them. | |
202 | This could go in kill-emacs-query-functions, to remind people | |
203 | to save their changes. If the user says yes, show them | |
204 | in a Custom buffer using customize-customized. | |
205 | ||
8c9676fb DK |
206 | ** Record the sxhash of the default value for customized variables |
207 | and notify the user (maybe by adding a menu item or toolbar button, | |
208 | as the detection can occur during autoload time) when the default | |
209 | changes (meaning that new versions of the Lisp source with a changed | |
210 | default value got installed) and offer ediff on the respective | |
211 | customization buffers. | |
212 | ||
e0402468 | 213 | ** Emacs Lisp mode could put an overlay on the defun for every |
8c9676fb DK |
214 | function that has advice. The overlay could have `after-text' like |
215 | " [Function has advice]". It might look like (defun foo [Function | |
216 | has advice] (x y) The overlay could also be a button that you could | |
217 | use to view the advice. | |
e0402468 | 218 | |
17e55b2a RS |
219 | ** Add a function to get the insertion-type of the markers in an overlay. |
220 | ||
9c9c88db SM |
221 | ** ange-ftp |
222 | *** understand sftp | |
1b2105d9 EZ |
223 | This is hard to make work because sftp doesn't print status |
224 | messages. | |
225 | ||
9c9c88db SM |
226 | *** Use MLS for ange-ftp-insert-directory if a list of files is specified. |
227 | ||
ba1c68de SM |
228 | ** Ability to map a key, including all modified-combinations. |
229 | E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up | |
230 | M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 -> | |
231 | H-S-C-M-s-double-wheel-up, ... | |
a9c1a157 | 232 | |
ba1c68de SM |
233 | ** Beefed-up syntax-tables. |
234 | *** recognize multi-character syntactic entities like `begin' and `end'. | |
235 | *** nested string-delimiters (for Postscript's (foo(bar)baz) strings). | |
236 | *** support for infix operators (with precedence). | |
237 | *** support for the $ (paired delimiter) in parse-partial-sexp. | |
238 | *** support for hook-chars whose effect on the parsing-state is specified | |
239 | by elisp code. Thus a char could both close a string and open a comment | |
240 | at the same time and do it in a context-sensitive way. | |
241 | *** ability to add mode-specific data to the partial-parse-state. | |
242 | ||
2d1ef312 RS |
243 | ** Add a way to convert a keyboard macro to equivalent Lisp code. |
244 | ||
ba1c68de | 245 | ** Have a command suggestion help system that recognizes patterns |
a9c1a157 RS |
246 | of commands which could be replaced with a simpler common command. |
247 | It should not make more than one suggestion per 10 minutes. | |
6165b6e3 | 248 | |
ba1c68de | 249 | ** Add a way to define input methods by computing them (when first used) |
30a2aafd RS |
250 | from other input methods. Then redefine C-x 8 to use a |
251 | user-selected input method, with the default being the union of | |
252 | latin-1-prefix and latin-1-postfix. | |
253 | ||
a7abe867 | 254 | ** Switch the Windows port to using Unicode keyboard input (maybe). |
2fa4f835 EZ |
255 | Based on http://msdn2.microsoft.com/en-us/library/ms633586.aspx, |
256 | this boils down to (1) calling RegisterClassW function to register | |
257 | Emacs windows, and (2) modifying ALL system messages to use Unicode. | |
258 | In particular, WM_CHAR messages, which result from keyboard input, | |
a7abe867 | 259 | will then come in encoded in UTF-16. |
2fa4f835 EZ |
260 | |
261 | One advantage of switching to Unicode is to toss encoded-kbd usage, | |
262 | which will solve the problem with binding non-ASCII keys with | |
263 | modifiers. | |
264 | ||
a7abe867 RS |
265 | Problem: using this on Windows 9x/ME requires installing the |
266 | Microsoft Layer for Unicode (MSLU), which might not implement all | |
267 | the required functionality that is available built-in on Windows XP | |
268 | and later. We should not make this change if it would pressure | |
269 | users of unauthorized copies of older versions of Windows to | |
270 | downgrade to versions that require activation. | |
271 | ||
ba1c68de | 272 | ** Implement a clean way to use different major modes for |
06382b71 RS |
273 | different parts of a buffer. This could be useful in editing |
274 | Bison input files, for instance, or other kinds of text | |
1b2105d9 EZ |
275 | where one language is embedded in another language. See |
276 | http://www.loveshack.ukfsn.org/emacs/multi-mode.el and also | |
277 | mmm-mode, as reference for approaches took by others. | |
a933dad1 | 278 | |
b76781cd RS |
279 | ** Arrange a way for an input method to return the first character |
280 | immediately, then replace it later. So that C-s a with | |
281 | input method latin-1-postfix would immediately search for an a. | |
282 | ||
ba1c68de | 283 | ** Give start-process the ability to direct standard-error |
a933dad1 DL |
284 | output to a different filter. |
285 | ||
ba1c68de | 286 | ** Make desktop.el save the "frame configuration" of Emacs (in some |
a933dad1 DL |
287 | useful sense). |
288 | ||
ba1c68de | 289 | ** Give desktop.el a feature to switch between different named |
8ba148c7 RS |
290 | desktops. |
291 | ||
ba1c68de | 292 | ** Replace finder.el with something that generates an Info file |
e39fc314 DL |
293 | which gives the same information through a menu structure. [Dave |
294 | Love started on this.] | |
a933dad1 | 295 | |
10bb671b RS |
296 | ** Add a cpio mode, more or less like tar mode. |
297 | ||
ba1c68de | 298 | ** Implement a variant of uncompress.el or jka-compr.el that works with |
2794f7ab DL |
299 | GNU Privacy Guard for encryption. [Code exists but isn't assigned. |
300 | See the Gnus development sources for assigned code concerning GPG | |
1b2105d9 EZ |
301 | use with mail, which is probably a good start.] See also |
302 | http://www.loveshack.ukfsn.org/emacs/auto-crypt.tgz. | |
a933dad1 | 303 | |
06382b71 RS |
304 | ** Save undo information in special temporary files, and reload it |
305 | when needed for undoing. This could extend undo capacity. | |
a933dad1 | 306 | |
ba1c68de | 307 | ** Change the Windows NT menu code |
a933dad1 DL |
308 | so that it handles the deep_p argument and avoids |
309 | regenerating the whole menu bar menu tree except | |
310 | when the user tries to use the menubar. | |
311 | ||
312 | This requires the RIT to forward the WM_INITMENU message to | |
313 | the main thread, and not return from that message until the main | |
0245b3ef | 314 | thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated |
a933dad1 | 315 | the whole menu bar. In the mean time, it should process other messages. |
d054101f | 316 | |
ba1c68de | 317 | ** Get some major packages installed: W3 (development version needs |
2794f7ab | 318 | significant work), PSGML. Check the assignments file for other |
a52ce7f8 | 319 | packages which might go in and have been missed. |
e39fc314 | 320 | |
ba1c68de | 321 | ** Make keymaps a first-class Lisp object (this means a rewrite of |
5dd31b13 SM |
322 | keymap.c). What should it do apart from being opaque ? |
323 | multiple inheritance ? faster where-is ? no more fix_submap_inheritance ? | |
324 | what else ? | |
e39fc314 | 325 | |
ba1c68de | 326 | ** Provide real menus on ttys. The MS-DOS implementation can serve as |
2fa4f835 | 327 | an example how to do part of this; see the XMenu* functions on msdos.c. |
e39fc314 | 328 | |
ba1c68de | 329 | ** Implement popular parts of the rest of the CL functions as compiler |
e39fc314 DL |
330 | macros in cl-macs. |
331 | ||
261b01c6 RS |
332 | ** Make compiler warnings about functions that might be undefined at run time |
333 | smarter, so that they know which files are required by the file being | |
334 | compiled and don't warn about functions defined in them. | |
335 | ||
ba1c68de | 336 | ** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA, |
a52ce7f8 | 337 | but it's a valuable feature worth making more general. |
e39fc314 | 338 | |
046ece71 | 339 | ** Support simultaneous tty and X frames. [See the multi-tty branch of Emacs |
4e8b322f | 340 | at http://lorentey.hu/project/emacs.] |
e39fc314 | 341 | |
ba1c68de | 342 | ** Provide MIME support for Rmail using the Gnus MIME library. [Maybe |
bf6394a6 DL |
343 | not now feasible, given Gnus maintenance decisions. fx looked at |
344 | this and can say where some of the problems are.] | |
e39fc314 | 345 | |
ba1c68de | 346 | ** Eliminate the storm of warnings concerning char/unsigned char |
1b2105d9 EZ |
347 | mismatches that we get with GCC 4.x and proprietary compilers on |
348 | various systems. They make it difficult to spot the important | |
349 | warnings. | |
e39fc314 | 350 | |
ba1c68de | 351 | ** Fix anything necessary to use `long long' EMACS_INTs with GCC. |
eaf67bae | 352 | |
ba1c68de | 353 | ** Split out parts of lisp.h and generate Makefile dependencies |
eaf67bae DL |
354 | automatically. |
355 | ||
ba1c68de | 356 | ** Update the FAQ. |
eaf67bae | 357 | |
ba1c68de | 358 | ** Allow auto-compression-mode to use zlib calls if zlib is available. |
b04f7626 | 359 | [It's required for PNG, so may be linked anyhow.] |
1265b539 | 360 | |
ba1c68de | 361 | ** Add a --pristine startup flag which does -q --no-site-file plus |
1265b539 DL |
362 | ignoring X resources (Doze equivalents?) and most of the |
363 | environment. What should not be ignored needs consideration. | |
364 | ||
ba1c68de | 365 | ** Improve the GC (generational, incremental). (We may be able to use |
7bea57c9 DL |
366 | the Boehm collector.) [See the Boehm-GC branch in CVS for work on |
367 | this.] | |
19cc91fb | 368 | |
ba1c68de | 369 | ** Check what hooks would help Emacspeak -- see the defadvising in W3. |
e2849090 | 370 | |
a5bd14d3 RS |
371 | ** Add definitions for symbol properties, for documentation purposes. |
372 | ||
ba1c68de | 373 | ** Add horizontal scroll bars. |
00a18b59 | 374 | |
ba1c68de | 375 | ** Provide an optional feature which computes a scroll bar slider's |
e4ded23c | 376 | size and its position from lines instead of characters. |
c0460c17 | 377 | |
ba1c68de | 378 | ** Add support for SVG (Scalable Vector Graphics) rendering to |
296808a5 | 379 | Emacs. |
6add099c | 380 | |
ba1c68de | 381 | ** Allow unknown image types to be rendered via an external program |
d1c3f6b6 RS |
382 | converting them to, say, PBM (in the same way as PostScript?). |
383 | ||
a420683a CY |
384 | ** Display images with alpha channels, such as png, with the current |
385 | background color of whatever frame it is displayed in. Currently, we | |
386 | use the default background color if specified in the png file, or, if | |
387 | that is unspecified, the background color of the frame in which the | |
388 | image was first created. Ideally, the image should display the | |
389 | background color of whichever frame it is being displayed in. The | |
390 | main complication is that this will require the loading of a new image | |
391 | object for each different background color. | |
392 | ||
ba1c68de | 393 | ** Allow displaying an X window from an external program in a buffer, |
d1c3f6b6 RS |
394 | e.g. to render graphics from Java applets. [gerd and/or wmperry |
395 | thought this was feasible.] | |
396 | ||
ba1c68de | 397 | ** Allow images (not just text) in the margin to be mouse-sensitive. |
d1c3f6b6 RS |
398 | (Requires recursing through display properties). Provide some way |
399 | to simulate mouse-clicks on marginal text without a mouse. | |
400 | ||
ba1c68de | 401 | ** Implement Lisp functions to determine properly whether a character |
d1c3f6b6 RS |
402 | is displayable (particularly needed in XFree 4, sigh). Use it to |
403 | define useful glyphs that may be displayed as images or unicodes | |
404 | (with ASCIIfied fallback via latin1-disp). Examples include | |
405 | box-drawing graphics in Custom buffers, W3 rules and tables, and | |
406 | tree displays generally, mode-line mail indicator. [See work done | |
407 | already for Emacs 22 and consult fx.] | |
408 | ||
ba1c68de | 409 | ** Do something to make rms happy with fx's dynamic loading, and use it |
d1c3f6b6 RS |
410 | to implement things like auto-loaded buffer parsers and database |
411 | access in cases which need more than Lisp. | |
412 | ||
ba1c68de | 413 | ** Extend ps-print to deal with multiple font sizes, images, and extra |
d1c3f6b6 RS |
414 | encodings. |
415 | ||
ba1c68de | 416 | ** Provide portable undumping using mmap (per gerd design). |
d1c3f6b6 | 417 | |
48b194fd RS |
418 | ** Make byte-compile avoid binding an expanded defsubst's args |
419 | when the body only calls primitives. | |
420 | ||
ba1c68de | 421 | ** Use the XIE X extension, if available, for image display. |
e641b454 | 422 | |
ba1c68de | 423 | ** Make monochrome images display using the foreground and background |
51fe665a RS |
424 | colors of the applicable faces. |
425 | ||
d101bf56 RS |
426 | ** Face remapping. |
427 | ||
ec68482b RS |
428 | ** Make `format-time-string' preserve text properties like `format'. |
429 | ||
fda12b27 RS |
430 | ** Optionally make the cursor a little thinner at the end of a line |
431 | or the end of the buffer. | |
432 | ||
ba1c68de | 433 | ** Add support for rendering antialiased text, probably using |
2a573e69 | 434 | XRender/Freetype. |
c5020b5b | 435 | |
ba1c68de | 436 | ** Port the conservative stack marking code of Emacs' garbage collector |
1b2105d9 EZ |
437 | to more systems, so that we can completely get rid of GCPROs. Note |
438 | that Boehm garbage collector provides this. | |
5e101746 | 439 | |
ba1c68de | 440 | ** Reorder defcustom's in each package so that the more important |
5005a9c0 EZ |
441 | options come first in the Customize buffers. This could be done by |
442 | either rearranging the file (since options are shown in the order | |
443 | they appear in the *.el files), or by adding a few :set-after | |
444 | attributes. | |
445 | ||
ba1c68de | 446 | ** Maybe document the features of libraries missing from the manual (or |
5e101746 RS |
447 | ancillary manuals, including the Lisp manual in some cases). |
448 | This is not worth doing for all of these packages and we need not | |
449 | aim for completeness, but some may be worth documenting. | |
450 | ||
451 | Here's a list which is probably not complete/correct: align, allout, | |
452 | artist, ansi-color, array, battery, calculator, cdl, cmuscheme, | |
657c5358 | 453 | completion, cua, delim-col, dirtrack, double, echistory, elide-head, |
5e101746 RS |
454 | easymenu, expand, flow-ctrl, format [format-alist], |
455 | generic/generic-x [various modes], kermit, log-edit, ledit | |
456 | [obsolete?], makesum, midnight [other than in Kill Buffer node], | |
457 | mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile, | |
458 | snmp-mode [?], soundex [should be interactive?], strokes [start from | |
459 | the web page], talk, thingatpt [interactive functions?], type-break, | |
460 | vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed, | |
461 | swedish, feedmail [?], uce, bruce, gametree, meese, page-ext, | |
462 | refbib, refer, scribe, sgml-mode, spell, texinfo, underline, | |
463 | cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml, | |
464 | cvs-status (should be described in PCL-CVS manual); other progmodes, | |
465 | probably in separate manual. | |
758830ba | 466 | |
ba1c68de | 467 | ** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap |
bf6394a6 DL |
468 | the XPMs so that the colour versions work generally. (Requires care |
469 | with the colour used for the transparent regions.) | |
470 | ||
ba1c68de | 471 | ** Convenient access to the `values' variable. It would be nice to have an |
758830ba JB |
472 | interface that would show you the printed reps of the elements of the |
473 | list in a menu, let you select one of the values, and put it into some | |
474 | other variable, without changing the value of `values'. | |
bf6394a6 | 475 | |
ba1c68de | 476 | ** (Controlled by a flag) make open and close syntax match exactly, |
c51b37fd DL |
477 | i.e. `(' doesn't match `]'. |
478 | ||
ba1c68de | 479 | ** Specify parameter ID-FORMAT in all calls to `file-attributes' and |
9ac8c83b LH |
480 | `directory-files-and-attributes' where attributes UID or GID are used. |
481 | Whenever possible, use value 'string. | |
482 | When done, change meaning of default value from 'integer to 'string. | |
483 | If value 'integer is used nowhere, remove the parameter ID-FORMAT from | |
484 | the definition of `file-attributes' and `directory-files-and-attributes' | |
485 | and from the calls. | |
486 | ||
a79a8781 EZ |
487 | ** Modify the emulation of `stat' for MS-Windows to support large files. |
488 | The current version uses the stock Windows definition of `struct | |
489 | stat', where the file's size is returned as a 32-bit integer. That | |
490 | overflows for files larger than 4GB. To fix, modify `stat' to use | |
491 | 64-bit size, and use a declaration of `struct stat' that supports | |
492 | such sizes. | |
493 | ||
cf4c9271 KH |
494 | ** Make language-info-alist customizable. Currently a user can customize |
495 | only the variable `current-language-environment'. | |
496 | ||
497 | ** Improve language environment handling so that Emacs can fit | |
498 | better to a users locale. Currently Emacs uses utf-8 language | |
499 | environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale | |
500 | are also put in utf-8 lang. env. In such a case, it is | |
501 | better to use Japanese lang. env. but prefer utf-8 coding system. | |
1f724d55 | 502 | |
321e4870 RS |
503 | ** Enhance locale handling: handle language, territory and charset |
504 | orthogonally and de-emphasize language environments. Use the locale | |
505 | to set up more things, such as fontsets, the default Ispell | |
506 | dictionary, diary format, calendar holidays and display, quoting | |
507 | characters and phrase boundaries, sentence endings, collation for | |
508 | sorting (at least for unicodes), HTTP Accept-language, patterns for | |
509 | directory listings and compilation messages, yes-or-no replies, | |
510 | common menu items when the toolkit supports it ... `locale-info' | |
511 | needs extending for LC_COLLATE &c. [fx started on this.] | |
512 | ||
1f724d55 KH |
513 | ** Eliminate the current restriction on header printing by ps-print. |
514 | Currently, a header can contain only single 1-byte charset in | |
515 | addition to ASCII. | |
516 | ||
517 | ** In ps-print, provide an user friendly interface to specify fonts. | |
518 | ||
519 | ** OpenType font support for various complex scripts (e.g. Devanagari). | |
520 | As X protocal doesn't provide a way to access OpenType Layout Tables | |
521 | in a OpenType font of a server side, we need a way to utilize local | |
522 | fonts (perhaps by directly using the Freetype library or indirectly | |
523 | via Xft library). | |
524 | ||
525 | ** Enhance word boundary detection for such a script that doesn't use | |
526 | space at word boundary (e.g. Thai). | |
527 | ||
cf4c9271 KH |
528 | ** Implement interface programs with major Japanese conversion server |
529 | in lib-src so that they can be used from the input method | |
530 | "japanese". Currently, most Japanese users are using external | |
531 | packages (e.g. tamago, anthy) or an input method via XIM. | |
1f724d55 | 532 | |
a53e64cc SM |
533 | ** Let LEIM handle the Mode_switch key like XIM does (i.e. a toggle like C-\ |
534 | but which can also be used as a modifier). | |
535 | ||
d59e3c42 NR |
536 | ** Improve Help buffers: Change the face of previously visited links (like |
537 | Info, but also with regard to namespace), add a forward button to make the | |
538 | Help buffer more browser like and gives the value of lisp expressions | |
539 | e.g auto-mode-alist, the right face. [nickrob@snap.net.nz has a patch | |
540 | for this for inclusion after 22.1]. | |
541 | ||
5a473319 GM |
542 | ** Possibly make `list-holidays' eval items in the calendar-holidays variable. |
543 | See thread | |
544 | <http://lists.gnu.org/archive/html/emacs-devel/2006-02/msg01034.html>. | |
545 | [rgm@gnu.org will look at this after 22.1] | |
546 | ||
9e21382c GM |
547 | ** Possibly make cal-dst use the system timezone database directly. |
548 | See thread | |
549 | <http://lists.gnu.org/archive/html/emacs-pretest-bug/2006-11/msg00060.html> | |
550 | ||
ba1c68de SM |
551 | * Internal changes |
552 | ||
41a023e3 | 553 | ** Cleanup all the GC_ mark bit stuff -- there is no longer any distinction |
dcbccc4d CY |
554 | since the mark bit is no longer stored in the Lisp_Object itself. |
555 | ||
1d919365 SM |
556 | ** Merge ibuffer.el and buff-menu.el. |
557 | More specifically do what's needed to make ibuffer.el the default, | |
558 | or just an extension of buff-menu.el. | |
559 | ||
560 | ** Use pcomplete by default in shell-mode. | |
561 | This means to make it behave (by default) more like the current code. | |
562 | Use it also for read-shell-command, M-x compile, ... | |
563 | ||
564 | ** Merge sendmail.el and messages.el. | |
565 | Probably not a complete merge, but at least arrange for messages.el to be | |
566 | a derived mode of sendmail.el. Or arrange for messages.el to be split | |
567 | into a small core and "the rest" so that we use less resources as long as | |
568 | we stick to the features provided in sendmail.el. | |
211fb124 | 569 | |
ba1c68de | 570 | ** Replace gmalloc.c with the modified Doug Lea code from the current |
1d919365 SM |
571 | GNU libc so that the special mmapping of buffers can be removed -- |
572 | that apparently loses under Solaris, at least. [fx has mostly done | |
573 | this.] | |
ba1c68de SM |
574 | |
575 | ** Rewrite make-docfile to be clean and maintainable. | |
576 | ||
577 | ** Add an inferior-comint-minor-mode to capture the common set of operations | |
578 | offered by major modes that offer an associated inferior | |
d3a403e5 SM |
579 | comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic. |
580 | For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode, | |
581 | haskell-mode, tuareg-mode, ... | |
ba1c68de | 582 | |
7cef6228 CY |
583 | ** Make SYNC_INPUT the default. |
584 | All loops using immediate_quit need to be checked to ensure that | |
585 | C-g can interrupt them, in case of an infinite loop. Once we | |
586 | switch to using SYNC_INPUT, we can remove the BLOCK_INPUTs in the | |
587 | allocation functions (allocate_string etc.) without worrying about | |
588 | data munging. | |
589 | ||
f57dad5a MB |
590 | ** Add "link" button class |
591 | Add a standard button-class named "link", and make all other link-like | |
592 | button classes inherit from it. Set the default face of the "link" button | |
593 | class to the standard "link" face. | |
594 | ||
2345130a SM |
595 | * Other known bugs: |
596 | ||
597 | ** a two-char comment-starter whose two chars are symbol constituents will | |
598 | not be noticed if it appears within a word. | |
599 | ||
07ff1e4b RS |
600 | ** Fix unexelf.c to handle the .data.rel and .data.rel.local |
601 | sections made by GCC 3.4 on IRIX. | |
